'Host CPU/memory/connection' on (HOST) changed from Green to Gray....then Gray to Green?

[edmandsj]

Hey Everyone,

I am trying to track down an issue with one of my two hosts. My Cluster (2 hosts in HA/vMotion) is fairly basic but runs lots of VM's that require 100% uptime (as if we want to accept less :smileywink: ). Below is the output that I receive every couple of weeks. It's a little concerning to know that for some reason a node is dropping out, or is it even dropping out? I don't see any vMotion alerts or tasks within this time frame. Nothing seems to break. Uptime on each VM and the node in question leads me to believe that nothing actually goes wrong, but it may be worse than I think. I mean it only does this for 17 seconds...how bad could it be, right?

I am assuming 'Host memory usage', 'Host cpu usage', 'Host service console swap rates', etc... are going from Green to Gray and then Gray to Green means that it is not a resource problem, just an indicator that it is "grayed out" because it has no information to report and/or a lost connection.

I suppose I am wondering if this is network related, host hardware related, vsphere related, or something I can't even think of. The host disconnects for 7 seconds and no vMotioning happens. I believe that 30 seconds is the rule before it vMotions? I mean, I'd rather not vMotion if I can avoid it.

Either way, what do you think?

My memory don't allow me to hold records for long :smileywink:. Last year I believe I have seen this problem and it was a bug. There were a patch for this also. It was a BUG which will bother you every now and then, trust me there was no problem at all from the environment perspective.

I don't remember the KB article or the patch revision talking about this, but you may need to look at the kb.vmware.com to see if you find any.
